Frequently asked questions
What is the source unit in this conversion?
The source unit is the hectopascal (hPa). Hectopascal is 100 pascal units.
What is the destination unit in this conversion?
The destination unit is the technical atmosphere (at). Technical atmosphere is kilogram-force per square centimeter.
How do I convert hectopascal to technical atmosphere?
Multiply the hectopascal value by 0.00102. For example, 10 hPa × 0.00102 = 0.010197 at.
Is the hectopascal to technical atmosphere conversion exact?
Yes. Both units are defined as fixed multiples of the pascal, the SI-derived unit of pressure, so the conversion factor follows directly from those exact definitions rather than a measured approximation.
Where is this conversion commonly used?
It's used whenever a value expressed in hectopascal needs to be compared with, or reported in, technical atmosphere, such as in engineering specifications, weather readings, tire pressure, or industrial and scientific work.
Can I convert technical atmosphere back to hectopascal?
Yes. Multiply the technical atmosphere value by 980.665 to get hectopascal.

About this conversion
This page converts hectopascal (hPa) to technical atmosphere (at) within the pressure converter.
Hectopascal is 100 pascal units. Technical atmosphere is kilogram-force per square centimeter.
The formula is technical atmosphere = hectopascal × 0.00102, based on each unit's fixed relationship to the pascal, the pressure converter's base unit.
The conversion is exact, since both units are tied to the pascal by a fixed numerical ratio rather than a measured or approximate value.
